“NHTSA Vehicle Safety Complaint – 2021 Kia Telluride I am the original owner of a 2021 Kia Telluride with approximately 78,000 miles. My vehicle has experienced recurring mechanical and drivability concerns, including an intermittent check-engine light, a previously reported camshaft-related diagnostic trouble code, and hesitation during acceleration. Of particular concern, there have been instances when I have pressed the accelerator pedal and the vehicle has hesitated before responding. This delayed acceleration creates a potential safety concern, particularly when entering traffic, merging, or navigating intersections where predictable engine response is essential. Additionally, the vehicle has exhibited rough operation while reversing and unusually harsh engine behavior when the automatic engine stop-start system engages. Despite multiple visits to a Kia-authorized dealership, including a monitored 1,000-mile oil consumption test, these concerns remain unresolved. The dealership advised that the vehicle passed the oil consumption test but subsequently recommended a dynamic engine cleaning procedure. I was informed that the technician was approximately 85%…”

“The sunroof on vehicle is not able to open/close correctly due to track/clips broken. Vehicle was purchased used January 2023. The sunroof has been used less than 5 times during this period. I spoke to a service advisor at the local dealership, Bulldog Kia of Athens , Ga. He confirmed that there is a continual issue with this and that He advises customers to NOT use the sunroof after 60,000 miles. With further research, Kia is aware of this issue and has yet to offer a solution. The cost to repair is $6000.00 for a new sunroof. There is a kit that could be used by dealers to repair.”

Electrical system

42 reports
“Vehicle was sitting all night and entered the garage in the morning and found the radiator fan at full speed. Car was not running, so backed it out, turned it off and the fan turned back on. Took it to a KIA dealer and kept it for a few days and just stated they couldn't duplicate the issue, although I couldn't get them to tell me technically what they checked. I kept the car parked outside for fear there might be an electrical issue and something overheats. Then was recently out and came out to my vehicle to find the fan running again. This time took multiple videos and it now consistently doing it. Took it home for the evening and disconnected the battery, and in the morning as soon as I reconnected the battery the fan started up to full speed again. Dropped it off to another KIA dealership and it was still doing it and showed it to the service advisor and gave him the videos. They are currently looking at it now. Also, there were never any warning lights or alarms that anything was wrong. There are so many postings out there on this issue on forums, FB, Telluride sites, etc., that I'm shocked there isn't at least a KIA TSB on this problem.”

“After having a recall, performed on the emergency parking brake it would engage while parked, but when trying to put it in drive or reverse, it would not disengage this began happening approximately two weeks to one month after the recall was performed. It isn’t happening constantly, but it does happen often. On occasion, while driving, it will engage and pull the car to the side nearly pulling me off the road. After looking for other instances of this online, I came across a post that stated it happens to their car, but only when it was over a certain temperature. After watching more closely, I had figured out that it only happens above 70F and it would only happen occasionally it was not every time it was above this . I have also brought it to the repair shop and they have no idea is what is causing it. I have found other postings about people having this issue with their Telluride same year. It is still occurring now and they are unsure of why or what is the cause.”

Power train

28 reports1 related recall
“I purchased my 2021 Kia Telluride S new, with only 22 miles from the test drive. XXX (approx. 53,000 miles, vehicle age 18 months): The transmission failed while I was traveling approx. 75-80 mph on a major highway in [XXX]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. first through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. XXX: Due to parts delays, the vehicle was not returned until November 2022 after the transmission work. XXX (approx. four months later): The vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. XXX (exact date unknown): While opening the sunroof at a stop, a loud crack occurred and pieces of the…”

“The contact owns a 2021 Kia Telluride. While the contact’s wife was driving approximately 60 MPH, the sunroof was open, and there was a loud sound coming from the sunroof, and metal pieces flew off the vehicle and fell inside the vehicle. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact that the vehicle was out of warranty. The failure mileage was approximately 75,833.”
